Do města přijíždí Pennyina "kamarádka" Christy, kterou však Penny nemá zrovna v lásce, a tak požádá Leonarda, zda by u nich nemohla přespat. Howard ihned využije toho, že Christy se vyspí s každým, kdo s ní bude chodit na nákupy, a s Christy se sblíží. Sheldon, Leonard a Rajesh poté řeší zdánlivě neřešitelné problémy způsobené Howardovou nepřítomností, například problém v čínské restaurace při objednávání. Poté, co se Christy pohádá s Howardovou matkou, je stabilita vesmíru obnovena a fyzikové mohou pokračovat ve své "Halo Night".

Penny's promiscuous friend Christy (Brooke D'Orsay) from Nebraska is in town, and ends up sleeping with Howard almost instantly, who is dragged to her. The pair takes over Penny's apartment, causing her to sleep on Leonard and Sheldon's couch for the night. With Howard gone, Penny takes his place playing Halo 3, causing Sheldon much distress as she is naturally good at it. Furthermore, Howard invites Christy to move in with him (and his mother), taking up all his time.

Sheldon is distraught over the odd number in the group believing they can no longer function. He is even more distraught when he invites Penny again to play Halo but she declines the offer to go dancing. Believing that they are falling apart as a group, the guys go to speak to Howard. When they arrive, they hear Christy and Howard's mother arguing loudly, causing Christy to leave. Howard, once again single, goes with the guys to play Halo and the group is restored yet again.
